Along with her latest Facebook update, Jill Kelly posted a picture of her husband hugging his father from his hospital bed in New York City.

"Jim Kelly's condition remains very treatable and potentially curable," said Dr. Peter D. Costantino, who will direct Kelly's treatment at Lenox Hill Hospital. "Our immediate focus is on controlling his pain and beginning the process of eradicating the cancer."

Kelly learned on March 14 that cancerous cells, which doctors removed from his jaw in June 2013, had returned. His wife said in a blog post last week that the cancer was "aggressive" and "starting to spread."

The 54-year-old Kelly, who was inducted into the Pro Football Hall of Fame in 2002, has received prayers and support across social media. The news of his surgery being canceled comes one day after Bills founder and owner Ralph Wilson died at age 95.
